WATER-CLOSET FLUSH-TANK.

Specification of Letters l atent.

Application filed June 14,1904. Serial No. 212,561.

To all whom it may concern:

Be it known that I, GILBERT S. THOMPSON, a citizen of the UnitedStates,residing at Cedar Rapids, in the county of Linn and State ofIowa, have invented certain new and useful Improvements in Water- ClosetFlush- Tanks, of which the following is a specification.

The object of this invention is to improve the construction offlush-tanks for waterclosets, so as to render them more durable,convenient, and easily repaired.

The nature of the invention will clearly appear from the description andclaims following, reference being had to the accompanying drawings, inwhicl Figure I is a front elevation of a flush-tank embodying myimprovements, a part of the outer casing being broken away to show theinner structure. Fig. 2 is a View from the rear and in perspective ofthe casing, a part of one corner being broken away to show details ofthe valve-trip. Fig. 3 is a perspective view of the inner tank with oneside removed to show the construction of the metal lining.

In the construction of water-closet flushtanks it is common to provide afinished hardwood tank lined with sheet-copper doubleseamed at thecorners and the seams soldered In the case of low-down tanks the tank isprovided with a cover; but the high tanks are usually left open. Afrequent diificulty met with in connection with such tanks is thenatural tendency of dampness to collect between the metal lining and thewood casing, especially in hot weather. This inner dampness (due to thesweating of the cooler inner lining) and the outer heat and dryness tendvery'soon to open the joints of the casing, greatly marring itsappearance if not destroying its utility. Another difficulty arises fromthe fact that electrolysis is very apt to destroy the solder on acoppertank-lining, and a leak soon takes place. This in vention is designed toremove these diificulties, as will be apparent from the descriptionfollowing. 7

Referring to the drawings, A is a tank, which may be a cheap and simplebox made of soft wood open at the top. This is lined, preferably, with aseamless lining of sheet metal, preferably copper. The lining is formedof a single sheet, folded at the corners in a Well-known way, flangedover at the edges B, and nailed to the upper edge of the tank. Thelining C needs no solder and is practically indestructible.

To the ends of the tank are attached brackets or cleats D and E, theformer being wide enough to furnish a ledge extending outside of anouter service-pipe F. This is carried up to the top of the tank, nearthe back side, and attached thereto by a flanged elbow G. To thisconnects an angle-valve H, and from this a down-pipe I extends down asfar into the tank as desired. Through a hole J in the bracket D runs arod K, connecting with the valve-lever L. At its lower end the rod isbent laterally, so as to engage a pin M, provided with asuitable buttonN and adapted to slide a limited distance in an adjacent part of theouter case P, which has a slot Q therein to take said pin. The outercase is made open on two sides, the back and bottom, and is made largeenough to slip easily over the entire tank and its connections,completely hiding them from view. It is provided with internal cleats Rto engage those at the ends of the inner tank. These cleats arepreferably inclined, as shown, so that the weight of the outer casingtends to make it fit tightly against the wall back of the tank. When inposition, the pin M projects inwardly just over the lateral bend in thetriprod K, and a downward push on the button N operates to flush thecloset, as will be understood.

The outer casing may be as costly and as highly finished as desiredwithout danger of opening joints, since there is no direct contact ofmoisture with it, inside or outside. It also obviates danger and injuryin setting or repairing the tank, inasmuch as it may be set aside whenany work is being done on the tank.

A further advantage incidental to this construction is that the dealermay exhibit a great variety in design or finish of cases without theexpense of tanks and connections for each, a single tank serving for thedisplay of all, provided, of course, that all are of the same size.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. The combination of a permanent flusht'ank forming a cistern for waternot under pressure, suitable feed and discharge pipes therefor, and aremovable ornamental casing therefor adapted to inclose and conceal thewater-tank on all sides except the back and bottom.

2. In a flushtank, the combination of a water-tank provided withsupports for an outer casing, a removable outer casing, and cleatsthereon to engage said supports.

3. In a flush-tank, the combination of a water-tank, a removable outercasing therefor, and inclined cleats to support the casing on the tankand close to the wall behind it.

4.The combination with a permanent water-tank forming a cistern forwater not under pressure, suitable feed and discharge pipes therefor, aremovable ornamental casing for said tank, adapted to cover and concealthe same on all sides except the back and bottom, supporting-cleats forsaid casing inside thereof, and engaging cleats on the tank, the feed orservice pipe passing up between the tank and casing, and discharginginto the tank at the top.

In testimony whereof I aflix my signature in presence of two witnesses.
